'ip heap-size' and 'ip6 heap-size' do not work.
-
According to the docs:
When working with a large set of routes, roughly exceeding 30,000 route table entries, TNSR may require additional memory to be allocated for the VPP dataplane Forwarding Information Bases (FIB). Smaller routing tables do not require special configuration.
However, setting these two settings makes VPP crash -- I've found that they end up in
/etc/vpp/startup.conf
asip { heap-size 1G }
andip6 { heap-size 128M }
to which VPP says in syslog that 'ip6 heap-size' is a parse error. Am I holding it wrong ? -
There was an issue with heap-size that will be corrected in version 20.10.1.
